Resurrection, the first
'The first resurrection,' mentioned in Revelation 20:5, 6, does not mean a first resurrection, but the essence and primary part of resurrection, which is salvation and eternal life. There is only one resurrection to life. A second does not happen, and is not mentioned anywhere in the Bible.

After this, I saw four angels standing at the four corners of the earth, holding the four winds of the earth, so that no wind would blow on the earth, or on the sea, or on any tree.
